fropper is an entirely new breed of toy! Bundles of bouncing and riding fun all rolled in to one, for toddlers 18-36 months. caster front wheels make cruising around safe and easy for young racers. and the built-in grip means you can just grab and go! we've also tried to make storage easier as fropper folds to a fraction of its riding size in just a few simple steps, without tools. fropper is ready right out of the box, no assembly required.
